Yes, that should work, but...

... under guix, $HOME/.guix-profile/{lib,...} is the standard prefix ;-)

So would it be possible to modify the test so that it takes LIBRARY_PATH 
into account? (If it were C, the AC macros would do that automatically.) Or 
could one simply use AC_CHECK_LIB?

If not, a possible work-around would be to check explicitly with the 
$HOME/.guix-profile/lib prefix.
